A cop pulls a guy over with a pickup truck full of penguins. He says:"You can't drive around with penguins in this town! Take them to the zoo immediately." The guy says OK, and drives off.
The next day, the cop sees the guy still driving around with the truck full of penguins, only now they're all wearing sun glasses. He pulls the guy over again and barks at him: "I thought I told you yesterday to take these penguins to the zoo?"
The guy answers back: "I did ... today we're going to the beach!"
